INDUSTRY 2 Overview Panasonic 

## **2 Overview** 

The PAN1781 is a Bluetooth 5.3 qualified[2] LE module based on the Nordic nRF52820 single chip controller. 

The Bluetooth 5.3 features additionally a higher symbol rate of 2 Mbps using the high speed LE 2M PHY or a significantly longer range using the LE coded PHY at 500 kb/s or 125 kb/s. The new channel selection algorithm (CSA#2) improves the performance in high interference environments. Furthermore, the new LE advertising extensions allow for much larger amounts of data to be broadcasted in connectionless scenarios. 

An output power of up to 8 dBm and the high sensitivity of the nRF52820 in combination with the LE coded PHY make the module very attractive in applications, where a long range is required. 

In addition, the ultra-low current consumption of the PAN1781 makes the module an ideal choice for battery powered devices. 

With the Cortex[-] M4 processor, 32 kB RAM, and the built-in 256 kB flash memory, the PAN1781 can easily be used in standalone mode, thereby eliminating the need for an external processor, saving complexity, space, and cost. 

The PAN1781 also supports angle of arrival (AoA) and angle of departure (AoD) direction finding using Bluetooth. 

A 128-bit AES/ECB/CCM/AAR co-processor may be used for on-the-fly packet encryption. 

For related documents please refer to  7.2.2 Product Information. 

For further information on the variants and versions please refer to  7.1 Ordering Information. 

> 2 The nRF52820 is also capable of Bluetooth 5.4, but the module is not yet qualified.

## **4.6 Access Port Protection APPROTECT** 

If using the APPROTECT version of the PAN1781 with order number ENW89857A3KF a special sequence of commands is necessary during production programming. These commands ensure that the built-in Bluetooth Device Address is preserved when the access port protection is enabled. 

The access port protection prevents (amongst others) any access to the built-in flash memory through the device debug port. 

In factory state, the PAN1781 with order number ENW89857A3KF implementing Nordic nRF52820 “revision 3 silicon” comes with the access port protection disabled.

## **Locking the Device Debug Port and enabling the Access Port Protection** 

Once the access port protection is enabled, no further access including debugging can be done anymore! 

To ensure that the device debug port is locked during production programming and the access port protection is enabled correctly, the following steps must be followed. 

1. Use the Microcontroller Development Kit (MDK) nRF MDK (version 8.40.2) or later for application development. 

   - If the application is based on nRF5 SDK (version 17.1.0) or later version, compile the application with the globally defined `ENABLE_APPROTECT` -define. Open the project in **Segger Embedded Studio** . Set the define in **Project** 

**options** > Section **Code** > **Preprocessor Options** > **Preprocessor Definitions** . 

   - If the application is based on nRF Connect SDK (version 1.8.0) or later version, compile the application with the option set `CONFIG_NRF_APPROTECT_LOCK=y` , for example in the project configuration file `prj.conf` . 

2. Use the nRF Command Line Tools (version 10.15.4) for production programming. Please make sure to use version 10.15.4 or later. 

3. Execute `nrfjprog.exe --verify fast --sectorerase --program` 

`application.hex` from a command line prompt to program an application HEX file: 

`Parsing image file. Verifying programming. Verified OK.` 

4. Execute `nrfjprog.exe --rbp ALL` from a command line prompt to enable the access port protection: 

`Protected the device against read and debug. Only a --recover, --debugreset, or --pinreset operations will work from now on.` 

It is possible to disable the access port protection again using the option `recover` , but the complete PAN1781 module is erased including the built-in Bluetooth Device Address. For details how to prevent this during application development, please refer to the “PAN1781 EVB User Guide (“Bluetooth Address Safeguard”)”. 

For technical details please refer to IN150 Informational Notice v1.0 in the Nordic Infocenter https://infocenter.nordicsemi.com/.

## **4.7 Antenna Placement Recommendation** 

## **Antenna “Keep out Area”** 

Do not place any ground plane under the marked restricted antenna area in any layer! This would be affecting the performance of the chip antenna in a critical manner. 

## **Impact of Placement on the Antenna Radiation Pattern** 

The placement of the module, surrounding material, and customer components has an impact on the radiation pattern of the antenna. 

The recommendation for the ground plane is based on a FR4 4-Layer PCB. 

The following requirements must be met: 

- ✓ The supply voltage must be free of AC ripple voltage (for example from a battery or a low noise regulator output). For noisy supply voltages, provide a decoupling circuit (for example a ferrite in series connection and a bypass capacitor to ground of at least 47 µF directly at the module). 

- ✓ This module should not be mechanically stressed when installed. 

- ✓ Keep this module away from heat. Heat is the major cause of decreasing the life time of these modules. 

- ✓ Avoid assembly and use of the target equipment in conditions where the module temperature may exceed the maximum tolerance. 

- ✓ Keep this module away from other high frequency circuits. 

- ✓ Refer to the recommended pattern when designing a board. 

The antenna requires a cutout area of 5 mm × 3 mm under the PAN1781 module. This “Keep out Area” shall be located in every layer under the module antenna. 

It is recommended to verify the perfect position of the module in the target application before fixing the design.

## **Antenna Placement Recommendation** 

All dimensions are in millimeters. 

Use a ground plane in the area surrounding the module wherever possible. 

- It is recommended to place the module: 

- In the center (horizontal) of mother PCB. 

- At the edge (horizontal) of mother PCB.

- Nordic IN150 Informational Notice v1.0 states “The new revision has no impact on CE, FCC/ISED or Bluetooth certifications unless the new pulse shaping filter is enabled.” 

- Nordic FTPAN-256 describes how to enable the pulse shaping filter, but as stated before it needs to remain disabled. Hence the code described in Nordic FTPAN-256 shall not be implemented/executed; otherwise the PAN1781 pre-certification becomes invalid. The Nordic FTPAN-256 workaround is meant for designs using an PA/LNA RF front end, which is not feasible with the PAN1781. Therefore, it is not useful to implement Nordic FTPAN-256.
